Quotas and Limits
Semaphore 2.0 enforces usage quotas and limits to protect customers and the platform from unforeseen spikes in usage. As your use of Semaphore expands over time, your quotas may increase accordingly.
- Quotas for Maximum Parallel Running Jobs in an Organization
- Pipeline and Block Execution Time Limit
- Job Log Size Limit
Quotas for Maximum Parallel Running Jobs in an Organization
Every organization has a set of quotas that define the maximum number of parallel running jobs.
Default quotas per machine type for a newly created organization:
|Machine Type||Default Quota|
If your organization needs are bigger than what is provided with the default machine quotas, you can request an increase by sending a request to firstname.lastname@example.org.
Pipeline and Block Execution Time Limit
By default, every pipeline and block is limited to an hour of execution time. This mechanism protects your project from undesired expenses in case of jobs that are running longer than anticipated. A good example is an accidentally committed debug statement that is waiting for user input.
This limit is adjustable in the Pipeline YAML.
version: v1.0 name: Using execution_time_limit agent: machine: type: e1-standard-2 os_image: ubuntu1804 execution_time_limit: hours: 3 blocks: - name: Limited to 3 hours by pipeline level configuration commands: - sudo apt-get install piglet - name: Limited to 15 minutes execution_time_limit: minutes: 15 commands: - sudo apt-get install vim
For detailed explanation, see the execution time limit section in the Pipeline YAML reference.
Job Log Size Limit
Semaphore collects up to 16 megabytes of raw log data from every job in a pipeline, which in practice roughly equals 100,000 lines of output.
Logs longer than 16 megabytes are trimmed with the following message on the bottom:
Content of the log is bigger than 16MB. Log is trimmed.
This limit is not adjustable.
For collecting longer textual files, or output from long and verbose process, we recommend using a blob store like AWS S3 or Google Cloud Storage.
